Bearing contaminated processing points

Bearing contaminated or rust should be how to deal with, to ensure the normal use of bearings it? Jintai self-lubricating bearing models to explain how to deal with:Washing oil, gasoline, ethanol, dehydrated liquid, neutral or alkaline cleaning agents can be used to clean the bearings. However, it should be noted that "petrol, wash oil, ethanol and
dehydrated liquids are flammable; alkaline cleaners are corrosive.The dangers of burning, exploding and decomposing with hydrogen chloride-based solvent oils can also be detrimental to health. When
cleaning the bearings can be used sharp brush, flat brush or non-woven
fabrics and other tools, once the solvent is evaporated after cleaning
immediately coated with anti-rust oil bearings. When the bearing with hardened oil or grease residue, the bearing can
be mechanically cleaned first, and then treated with a strong alkaline
material aqueous solution.1,
some enterprises in the process of producing bearings is not strictly
in accordance with the rules of cleaning rust-proof and oil seal
rust-proof packaging requirements of the bearing parts during assembly
and assembly of the bearing after the anti-rust treatment. Such as ferrules in the turnaround process is too long turnaround
time, the outer outer ring contact with corrosive liquids or gases.2, some enterprises in the production of rust-preventive lubricants,
cleaning kerosene and other products not meet the quality requirements
of process technology requirements.3, as bearing steel prices drop lower and lower, resulting in a gradual decline in bearing steel material. Such
as steel in the high content of non-metallic impurities (sulfur content
in the steel material so that the corrosion resistance of their own
decline), the microstructure deviation. Now the bearing steel used in manufacturing enterprises is more complicated, the quality of steel is more and more mixed beads.4,
some enterprises have poorer environmental conditions, high content of
harmful substances in the air, too small turnover space, and difficult
to carry out effective anti-rust treatment. Coupled with hot weather, production workers in violation of anti-rust
rules and other phenomena there is no shortage of existence.5, some companies rust-proof paper, nylon paper (bags) and plastic
tube bearing packing material does not meet the requirements of rolling
bearing oil seal rust-proof packaging is also one of the factors that
cause corrosion.6,
some enterprises bearing ring turning allowance and grinding margin is
too small, the oxide scale on the outer circle, decarburization layer
can not be completely removed one of the reasons.
